Two Limited ATTESA Watches Celebrate 50 Years of Citizen Eco-Drive
Two 1,500-piece ATTESA watches capture rare natural phenomena: the green flash and the aurora.
Citizen has released two limited-edition ATTESA watches to celebrate 50 years of Eco-Drive: the CC4084-83Z (Power of Green Flash) and the CC4085-81Z (Power of Purple Aurora). Each is limited to 1,500 pieces worldwide and will debut in October 2026, according to Citizen’s newsroom.
Citizen traces Eco-Drive’s origins to 1976, calling that first model the world’s first light-powered analog watch.
Both use the Cal. F950 Eco-Drive Satellite Wave GPS movement, which Citizen rates at ±5 seconds per month without signal reception. GPS sync takes as little as three seconds. There is a perpetual calendar, a 1/20-second chronograph running to 24 hours, world time, and a five-year run in power-save mode from a full charge.
Cases and bracelets are Super Titanium: Duratect DLC with Duratect Amber Yellow on the Green Flash, Duratect DLC with Duratect Pink on the Aurora. Citizen publishes no titanium grade beyond the trademark. It lists 44.6mm by 15.4mm for CC4084-83Z and labels that figure “design specification only.”
The dial work is where this earns attention, because Citizen names its methods: structural colour film, inkjet-printed black layers, vapour deposition. Of the aurora, Citizen writes that “the breathtaking purple colour can be seen in the night sky in polar regions when particles from the Sun collide with the Earth’s atmosphere.”
Projected global pricing is USD 2,515 for both.
Two notes on the edits I did not fully take. I kept “which Citizen rates at” on the accuracy figure, since ±5 seconds per month is the manufacturer’s rating rather than an independently verified one, and the same goes for the three-second sync. I also left “colour” and “vapour” in the dial paragraph because those words sit inside or adjacent to Citizen’s own quoted description of its methods and the direct quote that follows.

Note: Citizen's Japan-domestic release (citizen.co.jp) lists a yen price of ¥374,000 (¥340,000 before tax) for the Purple Aurora model, this is a separate market listing, not the USD figure, and should not be merged with the global price. |
